Well, wound the Time Capsule back to 7.4.2 and then reselected the backup drive on the 4 Leopards. Backups visible and happening. Alas not on the Snow Leopard MBAir. All backups are Finder visible - open the sparsebundle - but Time Machine sees nothing but the current state of the MBA. Finally fixed via a reboot and Command-Option-P-R. TM nows sees backups.
Hi
Our time Machine backups are no longer visible to Time Machine. 5 laptops backing up to 1 TB Time capsule - 4 10.5.x and 1 10.6.5. All the backups are visible on the drive but TimeMachine sees only one backup on my MBAir (10.6.5). Time Capsule is 7.5.2. My backup is 365 GB in the Time Capsule - drive is 256 GB. I can manually open the sparsebundle and see backups going back to October but TimeMachine see only 1 from a halfhour ago. I can see 74 backups in my wife's backups on the TC. When I checked her TimeMachine it needed to be reconfigured.
Did the 7.5.2 upgrade break something?
